Estimation of optimal laying period by Hybrids of Hy-line Brown production

Abstract

This research was conducted to determine the optimal laying period in commercial egg production. The research, which was carried out on 34900 Hy-line Brown chicks in a commercial enterprise, is completed between December 2002 and July 2004. The first twenty week period of the study occurred as chick growth, and 21st-80th weeks occurred as egg yield period. The optimal laying period was determined according to the Law of Diminishing Returns. In laying period, mortality was 8.17%; FCR 2.55; egg output 72%; total egg yield 302 number/hen and broken and fissured egg rate was 1.70%. In this period, components of costs as pullet were15.16%; feed 58.50%; labor 1.87%; veterinary and medicine 2.31%; energy 2.01%; viol 4.22%; general management costs 1.83%; maintenance-repair 1.66%; built-equipment depreciation 2.78%; hen depreciation were 9.66%. Estimated financial profitability was -0.01, with a profitability factor -0.01, and O/I rate were 0.96. The enterprise has made a profit (break-even point) between 40th and 41st weeks and reached maximum profitability between 54th with 55 weeks. After this point, continuing the production caused a loss for the enterprise. Therefore, input and yield prices should be considered in market and the production should be completed according to profitability of enterprise within the limits of the Law of Diminishing Returns
